Answer:

y+20 = 9(x+2)

Step-by-step explanation:

The slope that passes through the points is

m = (y2-y1)/(x2-x1)

= (79- -20)/ (9--2)

= (79+20)/(9+2)

= 99/11

= 9

We can use point slope form to write an equation. It says to use the first point.

y-y1 = m(x-x1)

y--20 = 9(x--2)

y+20 = 9(x+2)

Given the equation Y -3 equals 1/2 (X +6 )in point slope form identify the equation of the same line in standard form

liberstina [14]

The standard form of a line:

$Ax+By=C$

We have the equation of a line in the slope-point form:

$y-3=\dfrac{1}{2}(x+6)$ use distributive property

$y-3=\dfrac{1}{2}x+3$ add 3 to both sides

$y=\dfrac{1}{2}x+6$ multiply both sides by 2

$2y=x+12$ subtract x from both sides

$-x+2y=12$ change the signs

$x-2y=-12$
